Paving the Way for Self-driving Cars

The Impressive Contribution of Geomatics to Autonomous Driving
Since Karl Benz was granted a patent for his first internal combustion engine in 1879, the automotive industry has changed substantially. Or has it? The main principle remains the same: cars still have four wheels, a petrol- or diesel-powered engine – electric cars are still underrepresented and so far there are just a few hydrogen cars publicly available in select markets – and they still need to be driven by a human being. However, a major change is just around the corner: self-driving vehicles. And they won’t get far without geomatics technologies, claims Wim van Wegen, content manager of 'GIM International'....

ITC and UNU

Developments in Geomatics Education (8)
In 2005 ITC (International Institute for Geo-Information Science and Earth Observation) Enschede, the Netherlands, became an associated institution of the United Nations University (UNU) in a co-operation focused on disaster management and land administration. Described here are the role of UNU and the ITC contribution. For 32 years now the United Nations University (UNU) has been delivering research and capacity building to resolve global problems of concern to the United Nations (UN), its peoples and member states. UNU, an autonomous UN organ with as rector a UN under-secretary, fosters intellectual co-operation among scholars, scientists and practitioners, especially in the developing... (read more)

Point Clouds (2)

Survey of Processing Software
Collecting and processing point clouds has been trending topic in the geospatial sector over the past few years. This article focuses on point cloud processing software aimed at creating DEMs or DSMs and products derived from these. The first article of this diptych, originally published in the June 2014 issue of GIM International, focused on functionalities. This survey starts with the software of Terrasolid, which is based in Helsinki, Finland. It will then focus on three systems listed on the Geo-matching.com website, subsequently continuing with software which operates independently from the particular sensors, to then arrive at proprietary systems. It... (read more)

7 Questions about Hydrography and Its Relevance for Geomatics

The Perfect Combination of Science and Technology Applied to the Sea
According to NOAA (The U.S. National Oceanic and Atmospheric Administration), hydrography is the science that measures and describes the physical features of the navigable portion of the Earth's surface and adjoining coastal areas. It can be seen as an application area within the geospatial engineering discipline. We asked 7 questions to Laurent Kerléguer, the new director general of the French Hydrographic Office (Shom), to learn more about the world of hydrography. Chief weapons engineer Laurent Kerléguer was appointed director-general of Shom, the French hydrographic office, in July 2019. In this interview, GIM International asks him about the latest developments regarding the... (read more)

President of a Proud Organisation

GIM Interviews Dr Milan Konecny, President, International Cartographic Association (ICA)
Map users expect understandable, true and user-friendly output and visualisations of data fitted to application, and this is the job of the cartographer. The XXIII Congress of the International Cartographic Association (ICA) will be held in Moscow from 4th to 9th August 2007. Established in 1959 from origins in the International Geographical Union, ICA is soon to celebrate its fiftieth anniversary. Reason enough to interview ICA president Milan Konecny. Map users expect understandable, true and user-friendly output and visualisations of data fitted to application, and this is the job of the cartographer.

China Leaps Ahead with Geospatial Research

GIM International Interviews Professor Dr ZHANG Jixian
Prof. Dr John van Genderen, himself a leading western expert on geospatial developments in China, interviews Professor Dr ZHANG Jixian, acting president of the Chinese Academy of Surveying and Mapping on the rapid evolution of geospatial ideas in China. Could you provide a brief overview of China’s earth observation missions, from their start up until now? China initiated a plan to develop a self-owned, proprietary (in terms of intellectual property rights) earth observation system after DFH-1, the first Chinese satellite, in 1970. Since then, many earth observation missions have been launched. As of today, we have developed five series of... (read more)

Leica Geosystems, HDS

Fifth User Conference and HQ, San Ramon, USA
Terrestrial laser scanning combines a high level of detail with surveying accuracy for the creation of 3D-models of virtually any object. The technology literally opens up new dimensions and so attracts widespread attention. It is in the interest of manufacturers to bring these people together for cross-fertilisation of ideas, so to drive the makers on towards problem solving and new survey solutions. Leica Geosystems HDS held the fifth such get-together in California from 22nd to 24th October 2007.<P> Arriving tired and tense after an intercontinental flight, the journey from San Francisco International Airport to San Ramon feels fraught. After a... (read more)

Point Clouds and Smart Cities

The Need for 3D Geodata and Geomatics Specialists
The ‘smart city’ concept entirely relies on a permanent stream of massive amounts of data acquired by a great variety of sensors distributed throughout the city. Smart use of all this data requires integration with 3D city maps for which point clouds, acquired by laser scanning or photogrammetry, are the main sources. The author of this article identifies the abilities of point clouds to support the smart city concept. The benefits of point clouds for monitoring urban processes were recognised quite early on. Back in the early 1990s, airborne Lidar could accurately provide the height component which is so important... (read more)

Landsat: the Cornerstone of Global Land Imaging

Advancing the Understanding of Planet Earth
The Landsat satellites provide an uninterrupted space-based data record of the Earth’s land surface to help advance scientific research towards understanding our changing planet. In this article, the authors look at how the use of data from Landsat satellites has evolved over time to become a cornerstone of global land imaging with broad societal benefits. They conclude that the Landsat archive is poised to shift into a more real-time monitoring capability to help further our understanding of a changing Earth. Since 1972, the Landsat satellites have provided an uninterrupted space-based data record of the Earth’s land surface to help advance... (read more)

InSAR Used to Create Ground Stability Maps

Zooming on a Groundbreaking Revolution
Satellite radar interferometry (InSAR) is a technique that can measure millimetre-scale movement of the ground from space. It does this by comparing the return echoes, and thus the signal-path length, from two or more radar images taken over the same place, over time. Modern InSAR is now used by a range of industries concerned with ground or structural stability, from building development and control, to oil and gas production, to mining, to road and rail management. This article explains some key aspects of InSAR technology, including its innovative use to produce ground stability maps. Phase Shifters InSAR is based upon... (read more)
